When do you need a twin fuel pump?

jax4557

With yours and other people slightly lower daily numbers, I think I am going to get a couple hundred cc bigger injectors, the twin pump setup and maybe push for 700/550 on E85. The last dyno run I did for seb to get the ecutek controlling my boost solenoid was 620/550 at 14psi on my high setting. I dont want to go crazy on this stock bottom end but that would be a nice thing to say im able to change a map and be at 700hp for dyno outings and the occasional Mexico trips.

Side note, the RE-11 305's aren't cutting it at the 620/550... whats the next step for daily tires with some rain ability? Or am I in the brake change and tire change column if I want to use this power now?

Thanks Justin and congrats man!!
